Could you build this?
Partial It appears to be an open-source port or engine of 'jev' (grammar-constrained generation/decision making), requiring specialized knowledge of constrained context-free grammars and token sampling masking algorithms.
What it would actually take: A proper implementation requires modifying LLM logits sampling dynamically using trie-based or finite-state transducer (FST) grammar matching over token vocabularies. The stack typically involves Rust or C++ integration with model inferencing backends like llama.cpp or vLLM. The hard part is ensuring low-latency logit masking without stalling generation throughput across arbitrary grammar schemas.
